[₪] Primary Archetype: Chijutsu (血術, blood techniques) are a standard form of ninjutsu that enables its user to manipulate blood for the technique-specific purpose. While this may be misinterpreted as an extension of Water Release, or a nature transformation in general, it is simply a bodily mutation, meaning it is limited to a small circle of people, and in turn may not be replicated. This is because it enables its user's blood cells to multiply at rates not even categorized as alarming, essentially giving them an "infinite" amount of blood and leaving them invulnerable to death by bleeding out.
[₪] Secondary Archetype: Ninjutsu (忍術, ninja techniques) is a term referring to almost any technique which allows the user to do something that they otherwise would be incapable of doing, including the usage of weapons. Unlike genjutsu, which makes the opponent see illusions, the effects of ninjutsu are real. They vary greatly in purpose, with the simpler ninjutsu serving such tasks as transforming the user or allowing them to evade attacks. Shi's most effective utilization of ninjutsu is his use of killing intent, a general skill that he has adapted to a b-ranked level technique. By simply releasing his chakra, or showing the opponents his blood he is able to capture them within a terrifying "illusion" that grants them visions of their own grotesque and vile deaths at his hands, allowing him to inflict terror into almost anyone he sees.
[₪] Tertiary Archetype: Bukijutsu (武器術, weapon techniques) are techniques that entail the use of any handheld weapons in combat, whether the users be shinobi or samurai. Students of the Academy are taught the use of ninja weapons and tools like shuriken and kunai, learning how to throw and wield them through target practice. Bukijutsu can be used in combination with taijutsu, ninjutsu, genjutsu, chakra flow, and even other weapons in order to achieve more devastating effects. When used in combination with his blood techniques Shi is granted with a near infinite amount of weapons created from his own blood to use against the enemy, ranging from small shuriken to huge boulders made out of pure blood.

Shinsei's bodily fluid.. more specifically, his blood take on a unique and almost inhuman mutation or so to speak. The haematocyte contains ions with an unstable rate, giving his blood an almost 'electrical' charge. Whilst an inexperienced shinobi with a regular body would not be able to make full use of this, Shinsei is a user of ninjutsu that are.. eerily enough, based on the use of his blood. Whilst the increase in ions allows him to practically absorb electrical energy, such as lightning based techniques, into his own body to almost power-up his own blood stream, it comes at a price. If he was to absorb a mundane amount of electrical energy, the ions in his blood would begin to vibrate at an incredibly high frequency, and thus could explode; killing not only him, but a number of people within a fifty foot diameter. Whilst storing a substantial amount of ion energy in his blood cells, Shinsei's able to transmutate his blood into an odd form of plasma, as well as electrified blood, essentially granting him the ability to use his arsenal of blood-based techniques, but with plasma as a substitute, or blood that has taken on the ability to electrocute upon contact; which in turn makes him an incredibly deadly combatant.
